IEC 61850

Voltex Systems & Integration

IEC 61850 is intended to provide interoperability between a variety of devices (IEC 61850-7-2). However, the Conformance Statements required by Annex A do not make ALL communication features mandatory – manufacturers can choose which optional features they adopt.

Designers must be very familiar with these conformance statements (often not supplied with a standard user manual) before commencing any network philosophy or IED programming, especially in networks combining more than one brand of equipment (individual OEMs will not usually be aware of their “interoperability” with other OEMs devices).

GOOSE / MMS / SMV are not all supported by all OEM’s.
